Definitions

  • the invention relates to one-component, thermosetting compositions based on liquid rubbers which have a plastisol-like flow behavior. They are suitable both as flanged seam adhesives and as flanged seam seals in the automotive body shop, which simplifies logistics and application technology.
  • the invention further relates to a vehicle in which the flange seams are glued and / or sealed to the composition according to the invention after they have hardened.
  • Plastisols are generally understood to mean dispersions of organic plastics in plasticizers, which gel when heated to a higher temperature and harden when cooled.
  • the plastisols still used in practice today contain predominantly finely powdered polyvinyl chloride (PVC), which is dispersed in a liquid plasticizer and forms a paste.
  • PVC polyvinyl chloride
  • Such polyvinyl chloride plastisols are used for a wide variety of purposes. They are used, inter alia, as sealing compounds, for example for sealing seams in metal containers or as flanged seam adhesives in the metal industry and as corrosion protection coatings for metals (for example as underbody protection for motor vehicles).
  • Plastisols based on finely powdered methacrylate copolymers (PMMA) or styrene copolymers have become known. Plastisols of this type, especially those based on PVC or PMMA, are also used extensively in car body construction, for example for lining stiffening structures such as engine hoods, trunk lids, doors and roof structures, as well as for flange seams and for sealing seams from other joining processes.
  • PMMA finely powdered methacrylate copolymers
  • styrene copolymers are also used extensively in car body construction, for example for lining stiffening structures such as engine hoods, trunk lids, doors and roof structures, as well as for flange seams and for sealing seams from other joining processes.
  • the advantage of using plastisols for these purposes is their favorable flow behavior, especially at room temperature.
  • these plastisol compositions are often gelled in a pre-gelation process to such an extent that their viscosity is high enough to ensure this laundry resistance and initial strength of the components .
  • plastisol in the context of the invention relates exclusively to the rheological behavior and not to the composition of polymer powder (s) with plasticizer (s).
  • compositions based on vulcanizable rubber mixtures have recently been increasingly proposed as alternative adhesives or sealants and sealing compounds.
  • the EP-B-97394 describes an adhesive mixture based on a liquid polybutadiene rubber, powdered sulfur, organic accelerators and optionally solid rubber. It is known that such adhesives based on liquid polybutadienes can, by appropriate selection of the amount of sulfur and accelerators, achieve strength values which are equivalent to those of flexibilized epoxy adhesives. While these formulations have good hardening properties and good aging resistance and show reasonably useful adhesion even on normal oiled sheet steel, their applicability for the various galvanized steel sheets is unsatisfactory. In addition, the elongation at break of these high-strength rubber adhesives is very low. They cannot be injected and must be extruded at a higher temperature.
  • DE-C-3834818 propose to use OH-terminated polybutadienes for the liquid rubber.
  • the functional rubber polymer used can also be those with thiol, amino, amido, carboxyl, epoxy, isocyanate, anhydride or acetoxy groups, although the cured adhesive mixture has an elongation at break which Does not exceed 15%.
  • the WO 96/23040 describes one-component, heat-curing structural adhesives based on liquid rubbers, which may optionally contain a proportion of functional groups, solid rubbers, thermoplastic polymer powders and sulfur and also vulcanization accelerators. These are suitable for gluing metal parts. Tensile shear strengths of over 15 MPa with a simultaneous high elongation at break of over 15% can be obtained. These adhesives are particularly suitable for use in body-in-white in the automotive industry.
  • the rubber compositions of the aforementioned prior art are generally very suitable for their use in body-in-white in automobile production. They also have excellent properties in terms of laundry resistance, their aging resistance and the required technical properties.
  • a major disadvantage of these rubber compounds, however, is their very high viscosity, so that they can generally only be applied warm and pumpable. They cannot be applied using conventional spray methods, such as the airless method.
  • thermosetting rubber compositions which ameliorate this situation.
  • This document relates to a thermosetting reactive composition based on natural and / or synthetic, liquid elastomers containing olefinic double bonds and vulcanizing agents, these compositions at least one liquid cis-1,4-polyisoprene with a molecular weight between 20,000 and 70,000 as well contain a vulcanization system consisting of sulfur, accelerators and quinone oximes.
  • this composition can contain at least one further liquid polyene from the group consisting of 1,2-polybutadiene, 1,4-polybutadiene, polyisoprene, polybutene, polyisobutylene, copolymers of butadiene and / or isoprene with styrene and / or acrylonitrile, copolymers of acrylic acid esters with Dienes, wherein the molecular weight of the liquid polyene is in the range of 900 to about 40,000.
  • the liquid polyene (s) can additionally have terminal and / or randomly distributed carboxyl groups, carboxylic acid anhydride groups, hydroxyl groups, amino groups, mercapto groups or epoxy groups as functional groups.
  • compositions disclosed in this document generally do not achieve the high elasticity combined with high strength (in particular tensile shear strength) which is required for simultaneous use as a flanged seam adhesive and as a flanged seam sealer.
  • the invention is based on the knowledge that the object of the invention can be achieved by selecting suitable components in certain quantity ranges which, at least with regard to component c), are outside the range in WO 2002/048255 disclosed quantity ranges.

  • Its weight average molecular weight is preferably in the range of 1,500 to 3,000.
  • the composition preferably additionally contains, as further component d), 0.5 to 3.5% by weight, based on the total composition, of stereospecific polybutadiene which is liquid at 22 ° C. and has a vinyl-1,2 content in the range from 40 to 60 % and with a weight average molecular weight in the range from 1500 to 3000.
  • This component makes it easier to set the desired combination of properties after curing of the composition, which makes it suitable both as a flanged seam sealer and as a flanged seam adhesive.
  • This polymer contributes in particular to the necessary strength of the composition.
  • the adhesion of the composition according to the invention to metallic substrates is improved if it is used as further component e) 2 to 8% by weight, based on the total composition, of polybutadiene which is liquid at 22 ° C. and has carboxyl or carboxyl anhydride groups and a weight average molecular weight in the range contains from 1500 to 3000. This is therefore a preferred embodiment of the present invention. If necessary, additional tackifiers and / or adhesion promoters can be added.
  • hydrocarbon resins for this purpose, for example, hydrocarbon resins, phenolic resins, terpene-phenolic resins, resorcinol resins or their derivatives, modified or unmodified resin acids or esters (abietic acid derivatives), polyamines, polyaminoamides, anhydrides and anhydride-containing copolymers are suitable.
  • polyepoxy resins in small amounts can also improve the adhesion of some substrates. If tackifiers or adhesion promoters are used, their type and amount depends on the polymer composition and the substrate to which the composition is applied.
  • Typical tackifying resins such as terpene phenolic resins or resin acid derivatives are used in concentrations between 5 and 20% by weight, typical adhesion promoters such as polyamines, polyaminoamides or phenolic resins or resorcinol derivatives are used in the range between 0.1 and 10% by weight.
  • compositions according to the invention can optionally also contain finely divided thermoplastic polymer powders.
  • suitable thermoplastic polymers are polypropylene, polyethylene, thermoplastic polyurethanes, methacrylate copolymers, styrene copolymers, polyvinyl chloride, polyvinyl acetal and, in particular, polyvinyl acetate and its copolymers such as, for example, ethylene-vinyl acetate copolymers.
  • the particle size or particle size distribution of the polymer powder does not appear to be particularly critical, the mean particle size should be below 1 mm, preferably below 350 ⁇ m.
  • the amount of any thermoplastic polymer powder added is between 0 and 20% by weight, preferably between 2 and 10% by weight.
  • the crosslinking or curing reaction of the rubber composition has a decisive influence on the sealing function and the adhesive effect.
  • the vulcanization system must therefore be selected and coordinated with particular care.
  • the vulcanization system b) contains 6 to 10% by weight of sulfur and 0.25 to 20% by weight of vulcanization accelerator, based on the total composition. A large number of vulcanizing agents in combination with elemental sulfur are suitable for the vulcanization system.
  • vulcanization systems based on elemental sulfur, zinc oxide and organic vulcanization accelerators, including organic zinc compounds, are very particularly preferred.
  • the powdered sulfur is used in amounts of 6 to 10% by weight, based on the total composition. Quantities between 6 and 8% by weight are particularly preferably used.
  • Suitable organic accelerators are dithiocarbamates (in the form of their ammonium or metal salts), xanthates, thiuram compounds (monosulfides and disulfides), thiazole compounds, aldehyde / amine accelerators (e.g. hexamethylenetetramine) and guanidine accelerators.

  • MBT 2-mercaptobenzothiazole
  • ZMBT zinc salt
  • ZBEC diphenylguanidine and zinc dibenzyldithiocarbamate

  • particularly advantageous vulcanization properties and final properties of the cured rubber compositions are achieved when a combined vulcanization system of elemental sulfur and accelerator zinc compounds such as zinc salts of fatty acids, zinc dithiocarbamates, basic zinc carbonates and in particular finely divided zinc oxide is chosen.
  • An accelerator system composed of zinc oxide, ZBEC and ZMBT is particularly preferred.
  • the total content of zinc oxide and the organic compounds mentioned, in particular organic zinc compounds, is preferably in the range between 0.25 and 20% by weight.
  • Zinc oxide is preferably used in amounts from 3 to 7% by weight, in particular from 3.5 to 6% by weight, ZBEC in amounts from 0.5 to 2% by weight, in particular from 0.7 to 1.5 % By weight, and ZMBT in amounts of 0.2 to 1% by weight, in particular 0.3 to 0.7% by weight, in each case based on the total composition.

In particular, chalks, natural or ground calcium carbonates, calcium-magnesium carbonates, silicates, talc, barite and carbon black or graphite should be mentioned here. It can possibly be expedient for at least some of the fillers to be surface-pretreated. In particular, with the various calcium carbonates or chalks, a coating with stearic acid has proven to be expedient to reduce the moisture introduced and to reduce the moisture sensitivity of the cured composition.
  • the composition preferably contains 25 to 55% by weight, based on the total composition, of alkaline earth metal carbonate, preferably calcium carbonate (in particular in the form of chalk), which can be partially coated with fatty acid.
